United States Patent O 3,147,756 SMOKING PIPES Henry Schottier, 8MSCountry Club Lane,

' North Riverside, Ill. Filed Nov. 26, 1962, Ser. No. 240,104 2 Claims.(Cl. 1321-186) This invention relates to improvements in smoking pipes.More particularly, this invention relates to a condenser unit with afilter element for absorbing or collecting moisture and foraccommodating air-intake to cool the passing smoke.

One object of the present invention is to provide a condenser unit witha filter element for absorbing and/ or collecting moisture and productsof combustion in the smoke passage, said unit providing an opening forthe intake of air through the filter element to cool such element andthus enhance its effectiveness to cool and condense moisture frompassing smoke.

The above and other desirable objects of the invention will becomeapparent from the ensuing description, the appended claims and theannexed drawing, wherein:

FIGURE 1 is a side elevational View of a pipe equipped with a condenserunit embodying a preferred form of my invention.

FIGURE 2 is a fragmentary longitudinal sectional View taken through thestem and mouth piece of the pipe, shown in FIG. 1, and also takensectionally through the condenser unit.

FIGURE 3 is a view in cross section, taken at the line A-A of FIG. 2.

FIGURE 4 is a View corresponding to FIG. 2, but illustrating a modifiedform of the invention, wherein the condenser unit is mounted in anadapter capable of installation between the stern and mouth piece of aconventional pipe.

FIGURE 5 is a view in cross section, taken at the line B-B of FIG. 4about the principle axis of the cylinder formed thereby.

The smoking pipe P shown in FIGS. 1, 2 and 3 embodies a preferred formof this invention. Pipe P comprises the usual bowl B, a tubular stem 1and a tubular mouth piece 2. A smoke drawing bore in the stem 1communicates with a bore 17 in the mouth piece 2 which has an endportion 22 of reduced diameter telescoped into the bore 15 to detachablyassemble the parts 1 and 2. The bore 15 constitutes a socket at theouter end of stem 1 for receiving the stem portion 22. The lower sidewall 18 of stem 1 contains an opening 8 which leads laterally from thebore 15 outwardly through such side wall.

The condenser unit 3 comprises a filter carrier 19 constituting a singlebody of any solid substance which may be metal but is illustrated inFIGURES 2 and 3 as being of hard rubber or Bakelite. This filter carrierbody has an exterior portion 21 and an inner end 7 inserted into theside wall opening 8. A screw-thread connection is preferred between theparts 7 and 8. The inner end 7 of the filter carrier 19 contains arecess 9 constituting a holder socket for seating one end of a filterelement 4. Said filter element is preferably a porous body of fibrousmaterial (eg, cotton) and is shown as being cylindrical. The fibers ofthis body may be arranged heterogeneously or in any desired orderlyarrangement as is the case when first formed into a sheet and thenrolled into spiral convolutions of increasing diameter.

In each species of filter element there are formed myriad channelsextending lengthwise thereof to provide communication between the filterelement opposite ends and end portions. Channel means 10, shown in thedrawing as a single hole, communicates with the stem bore 15 through therecess 9 and side wall opening 8 and through 3,i47,75 Patented Sept. 8,1964 at least some of the myriad channels in the filter element 4. FIGS.4 and 5 illustrate the use of a filter adapter structure 5 disposedconnectively between the pipe stem 1 and the mouth piece 2. The tubularadapter 5 has a reduced diameter end portion 24 insertable into theouter end of the stem bore 15. The large diameter right end portion ofthe bore 15a in the adapter 5 is the same diameter as the bore 15 ofstem 1 wherefore end portion 22 of stem 2 is insertable thereinto asshown in FIG. 4.

Condenser unit 6 corresponds to condenser unit 3. It is formed with afilter-element-receiving recess 13 corresponding to the recess 9 and achannel means 14 corresponding to the channel means 10. A reduceddiameter end portion 11 of the condenser unit 6 fits into an opening 12in the adapter side wall 25.

It is preferred that the condenser unit 6 has a threaded portion 11 tomate with the threading in opening 12 to facilitate attachment anddetachment of the condenser unit with respect to the adapter structure5. The filter element 4 corresponds to that described in connection withthe previous embodiment.

The filter carriers I9 and 6 can have any desirable shape, which inthese embodiments provide a pipe stand or holder.

The new pipe invention operates as follows:

The hot smoke, passing the filter element 4, as shown by arrow A, willmix with cool air, passing through the filter element 4, indicated byarrow 16. Moisture in the hot smoke gases will condense and will beabsorbed by the filter element 4 which is cooled by the air entering at16. A cooler, cleaner smoke will enter the mouth.

It is easy to replace the filter element 4 after one or more smokes.

The carriers 19 or 6 can be attached to new as well as to old pipes. Inold pipes, only a matching hole 8 has to be drilled into the pipe stern1 and tapped when a threaded connection is employed.

Adapter structures 5 can be used for old pipes, eliminating drilling ahole in pipe stem 1.

The filter elements 4 can be impregnated with a slight amount of mint,menthol or any other desirable flavor to suit the taste of theindividual smoker.

While a limited number of embodiments described herein are at presentconsidered to be preferred, it is understood that various modificationsand improvements may be made therein, and it is intended to cover in theappended claims all such modifications and improvements as fall Withinthe true spirit and scope of the invention.

What is desired to be claimed and secured by Letters Patent of theUnited States is:

l. A combined pipe stand and filtering structure for a smoking pipe thatincludes a tubular stem which defines a smoke drawing bore and has anopening extending through the stem and communicating with the smokedrawing bore; which structure comprises a filter carrier; said filtercarrier being integrally formed with a first end portion and saidcarrier having a second enlarged and fiared end portion that isproportioned to provide a supporting base for a smoking pipe providedwith said combined structure; said first end portion of said carrierbeing proportioned to mate with and be removably maintained within theopening provided in the stem of the smoking pipe; said filter carrierhaving a recessed region and an air circulating hole provided therein;said recessed region extending through said first end portion of saidfilter carrier so as to communicate with the smoke drawing bore whensaid first end portion of the filter carrier is positioned within theopening provided in the pipe stern; said air circulating holecommunicating with said recessed region and extending through saidsecond end portion of said carrier to thereby provide a passage forcooling air to the smoke drawing bore; and an absorbent myriad channeledproportioned to matingly connect the tubular stern and a 10 tubularmouth-piece of the smoking pipe, said lter adapter being provided with asuitably proportioned hole for receiving said rst end portion of saidfilter carrier.
